This topic describes the issues that may occur when you use the feature of function partitioning key-based routing in OceanBase Database Proxy (ODP) and provides corresponding solutions.
The routing based on an expression is inaccurate.
First, check whether ODP supports the function in the expression. Then, check whether the function syntax used is supported.
A routing error occurs because scientific notation, such
1e9, is used in the expression.Currently, ODP does not support the calculation of expressions with scientific notation.
A routing error occurs because a function argument contains a column name, such as
c1 +1andmod(c1,2).Currently, ODP does not support the parsing of expressions with column names.
